The DoD 8140 manual lists fewer than 20 certifications that satisfy its highest technical security tiers. CASP+ certification is one of them — and it's the only CompTIA credential that lands you there without requiring a sponsoring organization to vouch for your experience before you can even register to test. For defense contractors and federal IT professionals, that's a meaningful practical advantage. For everyone else, it's a signal that this exam is taken seriously in environments where credentials actually get audited.
This guide covers what's on the CAS-004 exam, how to prepare for it, what it costs, and what kind of work it actually leads to — based on the certification's current requirements and the job market for senior security practitioners.
What Is the CASP+ Certification?
CASP+ (CompTIA Advanced Security Practitioner) is a vendor-neutral, advanced-level cybersecurity certification issued by CompTIA. The current exam version, CAS-004, was released in April 2023. It sits above Security+ in CompTIA's credential stack and targets security architects, senior security engineers, and technical leads who make security decisions rather than just implement them.
The certification's positioning is often misunderstood. CASP+ is not a management certification — it's deliberately technical. CompTIA designed it to validate hands-on decision-making in complex environments: hybrid cloud architectures, zero-trust implementations, secure DevOps pipelines, and incident response at the enterprise level. That's what distinguishes it from CISSP, which leans heavily on governance, policy, and risk management frameworks.
Key facts about the CASP+ certification:
- Exam code: CAS-004
- Question format: Maximum 90 questions; mix of multiple-choice and performance-based items
- Time limit: 165 minutes
- Passing score: No scaled score — pass/fail only
- Renewal: Every 3 years via continuing education or retesting
- Compliance: ISO 17024, DoD 8140/8570 IAT Level III and IAM Level II/III
- Recommended experience: 10 years general IT, with at least 5 in hands-on security roles
The pass/fail scoring model is worth noting. CompTIA doesn't publish a numerical passing threshold for CASP+ the way it does for Security+ (where 750 out of 900 is the cutoff). This makes it harder to benchmark your readiness using practice exam scores alone.
What's Actually on the CASP+ Exam (CAS-004 Domain Breakdown)
CAS-004 is organized around four domains. Understanding the weight of each is essential for allocating study time correctly.
Security Architecture (29%)
The largest domain covers enterprise and cloud security architecture, including zero-trust frameworks, software-defined networking, identity federation, and secure integration of on-premises and cloud systems. Expect scenario-based questions where you're choosing between architectural approaches, not just identifying definitions.
Security Operations (30%)
This is the heaviest domain by weight. It covers threat intelligence, incident response, vulnerability management, and security monitoring at scale. Performance-based questions in this domain often simulate log analysis, configuration review, or selecting appropriate defensive controls given a set of constraints.
Security Engineering and Cryptography (26%)
Covers PKI, cryptographic protocols, hardware security modules, secure coding practices, and enterprise mobility. This domain is where candidates without a deep technical background tend to struggle — it assumes you've actually worked with these systems, not just read about them.
Governance, Risk, and Compliance (15%)
The smallest domain, but don't dismiss it. Questions here require applying risk frameworks (NIST, ISO 27001) to specific scenarios, understanding privacy regulations, and interpreting the business impact of technical security decisions. This is where CASP+ overlaps most with CISSP material.
Who Should Pursue the CASP+ Certification — and Who Shouldn't
CASP+ is the right credential if your day-to-day work involves making technical security decisions at a systems level, not approving them in a committee. Security architects, senior penetration testers transitioning into architecture roles, lead incident responders, and senior cloud security engineers are the natural audience.
It's also strategically useful if you work in or around federal contracts. CASP+ satisfies DoD 8140 requirements for several privileged access roles that CISSP doesn't cover at the same technical tier. If your employer needs you to maintain a specific DoD IAT or IAM level, check the 8140 manual before defaulting to CISSP.
Who shouldn't pursue it right now:
- Candidates with fewer than 5 years of hands-on security experience. The exam's performance-based items are built around pattern recognition from real-world scenarios. Without that experience base, preparation takes significantly longer and retention is weaker.
- Professionals whose primary goal is moving into management. CISM or CISSP will serve that trajectory better, since hiring managers for security director and CISO roles look for those credentials first.
- Those who just want to check a compliance box. CASP+ requires renewal every three years and continuing education. If you're not actively working in a technical security role, maintenance becomes a burden without a corresponding career benefit.
CASP+ Certification Cost and Renewal
The exam voucher costs $509 USD through CompTIA directly. Third-party retailers and training providers sometimes offer discounted vouchers, so it's worth checking before purchasing at full price. CompTIA also offers a CertMaster bundle that packages the exam with practice materials, typically in the $700–900 range depending on what's included.
Renewal happens every three years. You have two options:
- Continuing Education (CE) credits: Earn 75 CEUs during the three-year cycle through qualifying activities — training courses, conference attendance, publishing, or passing other certifications. This is how most active practitioners renew without retesting.
- Retake the exam: Passing CAS-004 (or whatever the current version is at renewal time) resets your certification period.
The CE renewal model also means that passing a higher-level certification — like CISSP or a vendor security cert — can count toward your CASP+ renewal CEUs, which makes stacking credentials more efficient if you're planning a multi-certification path.
Total first-year cost for most candidates, including study materials and the exam voucher, realistically falls between $700 and $1,200 depending on course selection and whether you need multiple exam attempts.
Career Outcomes: Jobs and Salary After CASP+ Certification
The CASP+ certification shows up most frequently in job postings for senior security engineer, security architect, information systems security officer (ISSO), and information systems security manager (ISSM) roles — particularly in the defense and federal space, where DoD 8140 compliance drives requirements.
Salary ranges for roles that commonly list CASP+ as a requirement or preference:
- Senior Security Engineer: $110,000–$145,000 (national median, US)
- Security Architect: $130,000–$165,000
- ISSO/ISSM (cleared, federal contractors): $120,000–$160,000+, with cleared positions often at the higher end
- Cloud Security Engineer (senior): $125,000–$155,000
It's worth being direct about something: CASP+ is not a salary-driver the way CISSP is in the private sector. In commercial environments, CISSP carries more name recognition with hiring managers and HR systems. CASP+'s compensation leverage is strongest in federal and DoD-adjacent roles where it satisfies specific compliance mandates that CISSP doesn't fully cover at the technical tier.
If your career is in commercial security, CASP+ is still worth pursuing if it reflects your actual technical depth — but pair it with cloud provider security certifications (AWS Security Specialty, Google PCSE) for broader private-sector appeal.

CASP+ Certification FAQ
Is CASP+ harder than CISSP?
They test different things, which makes direct comparison tricky. CASP+ is technically deeper — the performance-based questions require applied judgment in scenarios involving actual system configurations and architectural trade-offs. CISSP covers a broader range of domains but at lower technical depth. Candidates with strong hands-on security backgrounds often find CASP+ more straightforward than CISSP; those coming from management or governance roles tend to find the opposite.
Does CASP+ satisfy DoD 8140 requirements?
Yes. CASP+ satisfies DoD 8140/8570 requirements for IAT Level III (the highest technical tier for information assurance technician roles) and IAM Level II and III. It also covers IASAE (Information Assurance System Architect and Engineer) Level I and II. If you're working on cleared programs or federal contracts, verify the specific role requirements against the current DoD 8140 manual, as it gets updated periodically.
What's the CASP+ pass rate?
CompTIA doesn't publish official pass rate data for CASP+. Anecdotally, community estimates run between 50–60% on first attempt, though this varies significantly based on candidate preparation and relevant experience. The pass/fail scoring model (no numerical score released) means you can't gauge how close you came if you don't pass — plan for the possibility of a retake when budgeting.
Can I take CASP+ without Security+?
Yes. CompTIA states the recommended experience but doesn't enforce prerequisite certifications for exam registration. You don't need to hold Security+ to sit for CASP+. That said, the Security+ curriculum overlaps with approximately 20–25% of CASP+ material, and candidates without that foundation typically need more preparation time on foundational concepts before tackling the advanced content.
How long does it take to prepare for the CASP+ exam?
For candidates who meet the recommended experience baseline (5+ years hands-on security), most structured preparation plans run 8–12 weeks with consistent daily study. Candidates with gaps in specific domains — particularly security engineering or cryptography — should plan for the longer end of that range. Without the underlying experience, preparation time increases substantially because you're building foundational knowledge alongside exam-specific prep.
Is CASP+ worth it in 2025 if I already have Security+?
It depends on your target role. If you're pursuing DoD or federal work, the jump from Security+ to CASP+ is often necessary rather than optional for higher-tier positions. In commercial environments, the credential signals advanced technical depth, but the salary impact is more modest than CISSP unless you're specifically targeting roles where the DoD compliance angle applies. The credential is most valuable when it accurately reflects what you do day-to-day — it's a weak investment if you're managing security programs rather than engineering them.
Bottom Line
The CASP+ certification is the right credential for senior security practitioners who work at the technical decision-making level and operate in or adjacent to environments where DoD 8140 compliance matters. It's not a substitute for CISSP in commercial management tracks, and it's not an entry-level step up from Security+ — the experience requirement is real, and the exam tests it.
If you're in the target profile, start with a structured CAS-004 course to cover the current domain weighting, then shift to performance-based practice questions in the final weeks of preparation. The pass/fail model punishes candidates who underestimate the applied judgment component of the exam.
For most candidates, the combination of the CompTIA CASP+ (CAS-004) course for domain coverage and the Wiley study guide for reinforcement covers the preparation ground effectively.
